Preparation and polymerization of isopimaric acid derivatives

Isopimaric acid is a typical rosin compound and can account for 30% of the total mass of slash pine rosin. The molecular structure of isopimaric acid derivatives features an unsaturated double bond at the C13 position, opening up the possibility of their industrial polymerization. In this study, isopimaric acid (95.4%), methyl isopimarate (99.5%), and allyl isopimarate (95.1%) were prepared as highly pure monomers. New experimental results are presented and mechanisms based on the investigation of free-radical polymerization under UV irradiation are proposed. New rosin monomers for potential value-added utilization of woody biomass are also identified. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136, 47817.

Diagnosis and treatment of suppurative complication of anaerobe etiology in trauma and orthopedic patients

An extensive study of road traffic accident cases occurring within eastern suburban Calcutta during April 1992 to March 1993 was done. Of which 276 fatal cases having minimum medical aids were taken into consideration to avoid erroneous interpretation. Male pedestrians of age group of 50 years and above were mostly involved during the time period of 5 A.M. to 12 Noon. Fatal Accidents mostly occurred during winter and on the broader roads (Highways) and in majority of cases victims were at fault.     

不清根手工双面焊材料及工艺研究

本文分析了中厚板传统手工双面焊存在的诸如打底焊焊缝质量无法保证，需用碳弧气刨清根；工人劳动强度大；生产效率低；焊接质量不稳定等主要问题。为提高打底焊焊道质量，不用清根使背面得到良好的凹成形，研制了适合Ｘ形坡口的梯形体陶瓷衬垫。探讨了焊缝背面成形的主要影响因素及控制方法。     

发射药包装用复合纸桶现状与国内外纸桶对比
